In -orde'r fthat'the construction, the operation, andthe:ad-vari-tages.of my invention may be more fully understood :and appreciated, I will now take up a; `detaileddescription thereof, in which I will i set forth the same `as fullyandascomprehensively as YI may.

In thefdrawing, :the numeralrl denotes the body portion oct my machine, 'Said body portion having thebase Aportions 2 'and formed integrally therewith and extending 4outwardly therefrom. The base portions? -:and 3 have the slots 12' Iand 3'A formed therebetween for the rpurpose hereinafter set forth: Each of the outwardly extending portions 2 and- "3` have :smooth-bored apertures 2 and 3 respectively formed therethrough, said apertures 2"" and 3" being parallel with relation tofeach other. `The body portion `l also has the forwardly extending '.lugs`f4, 15,16 and l formed integrallyktherewith, leach -of `said lugs having an aperture formed therethrough for the reception of the threadedfbolts f8 landt, the bolt 8 extending` through ztheapertures which are formed through the lugs 4 and 5, and the bolt `9 extending through the apertures which are formed through'the lugs G :and'l and "for @the -.purpose hereinafter set forth,` Thelugs :14, 5, 6 and I :also provide .guides for the adjustable-stop lHI r.which is slidably located therebetween. The stop I 0 has the rearwardly ext'endingsidemembers t0' formedintegrally therewith,\izsaidrside members t0 being adapted Ito contactfone A:of the innerssurfaces `oi" each of the forwardly extending lugs 4, '-5, 6 and l, said ad- .instable .stop member t0 also has the rearwardly with, said ,fingers .having the slots `Ill,a formed therebetween, .for the purpose hereinafter set forth. Extending rearwardly yfrom ythe .central portion of the member l0 are `the threaded stems Il!"J and IUQ, said stems being `adapted to register with the smooth-bored apertures I and '1"' of the m'em'ber 'l. 'Threaded onto the stems I 0b and illcarelthe adjusting nuts 'Hld and Ille, said adjusting nuts being formed 'circular in shape and having their =`outerperipheres serrated as shown irrFigure.

' Extending-forwardly from the `members r2 and 3; sand hingedly .securedthereto are the jaw-holding members I l, each of said members Il I have the portions I I' formed integrally therewith and extending at right angles thereto, said portions I I having the smooth-bored apertures IIa formed. therethrough, each of said apertures IIa being adapted to register with the apertures 2" and 3, and each of the members II being hingedly secured to their respective base portions 2 and 3 by the bolts 28 and 2S respectively. Extending through the central portion II is the circular aperture IIb and the slotted aperture IIC, the purpose of which will be hereinafter set forth.

Extending outwardly from between the lugs 4 and 5 is the threaded hinge-bolt I2, said hingebolt I2 being secured therebetween by means of the bolt 8, and likewise, extending outwardly from between the lugs 6 and I is the hinge-bolt I3, said hinge-bolt I3 being hingedly secured therebetween by means of the bolt 9. bolts I2 and I3 have the head portions I2 and I3 respectively formed integrally therewith, each of the head portions havingan aperture formed therethrough, andthrough which the respective bolts 8 and 9 are secured.

Secured to the jaw-holding members I I are the `iaw members I4, each of said jaw members I4 having an aperture I4 formed therethrough and each of said apertures I4 being adapted to register with its respective hinge-bolt. Also formed through the member I4 is the threaded aperture I4", through which the jaw members I4 are secured to their respective jaw-holding members I I by means of their respective screws I 5. The jaw members I4 extend forwardly and then curve inwardly forming the curved portion I4a, and terminate by forming the blade portion I4b. The jaw members also have formed integrally therewith the shoulder portions I4?l which is adapted to be clamped against the outer surface of an armature. Projecting rearwardly and angularly from one end of the curved portion I4HL is the arm portion I4c and which is adapted to guide a wire into the slots of an armature during the process of winding the same.

On each of the threaded hinge-bolts I2 and I3 are the respective coil springs I6 and I'I, one end of each being adapted to press against the head portion of its respective hinge-bolt, and the opposite end of each of said springs being adapted to exert pressure against the inner face of itsv respective jaw member I4.

Threaded onto the outer end of each of the hinge-bolts I2 and I3 are the wing-nuts I8 and I9 respectively, and which are adapted to be turned against their respective jaw-holding members I I.

Extending rearwardly from the body member I is the shaft 20, and which may be formed integrally therewith or attached thereto in any well known manner. The shaft is adapted to extend through a bearing block 2I which is supported by the bracket 22, and which is adapted to be secured to a bench 2l or other suitable support by means of the bolts or lag screws 23. The shaft 20 is adapted to have a crank 26 attached to its rear end as shown in Figure 1. v

When it is desired to operate my machine by power, the shaft 20 may be detached therefrom and the base portion securedto -the face plate of a lathe or other power machine by means of bolts inserted through the slots 2' and 3.

The numeral 24 denotes an armature having the slots 24 formed therethrough, and25 denotes the wire which my machine is adapted to 'wind onto the armature.

The hinge- The operation of my machine is substantially as follows- With the jaw members I4 extended as shown in Figure 1, the armature 24 is inserted therebetween, the stop I being adjusted, by the nuts IIId and IIJe so that the armature 24 is in position for the blade portions I IIb to engage two of the slots 24'. Only the blade portions I IIb extend into the slots 24 and the shoulder portions I 4d are clamped against the outer periphery of the armature 24 by tightening the wing-nuts I8 and I9 against their respective members II, to

which the jaw members I4 are secured. After the armature 24 is thus secured between the jaw members I4, as shown in Figure 1l, a wire 25 is -drawn from a spool (not shown) to the armature,

and the free end of the wire is then secured in one of the slots IIJEL where it is held securely, and the machine is then ready for operation.

As the crank 26 is turned, causing the shaft 20 to rotate, which being secured to the body portion I, and causing the entire machine, together with the armature, to rotate. As the armature is rotated, the wire 25 being held securely in one of the slots Ia, is drawn around the armature, the arms I4c of the jaw members I4 guide the wire 25 toward the curved portions I4a of the members I4, after which the wire 25 is guided by the jaw members into the respective slots 24 of the armature 24. After the correct number of turns of wire have been wound into the first pair of slots 24 and the wire removed from its slot IIJa, one of the wing-nuts is loosened and thereby releasing one of the blade portions I4b from its respective slot 24. The armature 24 is then rotated until the succeeding slots 24 are in register with the blade portions I 4b, the wing-nut is again tightened against its respective member II, and the shoulders I4@1 are in clamped relation with the armature 24, after which the free end of the wire 25 is again secured in one of the slots Il)a and the operation of winding the wire is repeated.

The above described operation is repeated until all of the slots have been properly wound with the wire, and the completely wound armature is removed.

When it is desired to wind an armature having hellcally extending slots, the screws I may be loosened and the jaw members I4 pivoted so that the blade portions I Ib thereof will conform to the angularity of said armature slots, after which the screws I5 may be tightened, and thereby holding the jaw members in the required position.

I desire that it be understood that my machine may be operated by a power lathe or the like as efi'iciently as with a hand crank.

I also desire that it be understood that minor changes may be made in the several details, and in the arrangement of the parts herein shown and described, without departing from the spirit of my invention or sacrificing any of the advantages thereof which are new and useful, and which involve invention.

Having now fully shown and described my invention, what I claim and desire to secure by each of which is adapted to be removably secured ing members hingedly secured to said base porto `said hinged members, each of said jaw members having a rearwardly and outwardlyprojecting arm, blade portions carried by said jaw members and adapted to engage the edge of a slot in an armature, shoulder portions carried bythe jaw members andadapted to be secured against the outer surface of an armature, said projecting arms being adapted to engage and to guide a wire into the slots of an armature, and means for holding said jaws in clamped relation with an armature.
